Best Practices
Grounding Best Practices
Electronic components are sensitive to electrostatic discharge (ESD). Please use precaution and wear
protective gear and gloves when handling electronic components.
A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or micro-
circuitry. To prevent this from occurring, it is recommended to wear gloves and wrist strap with a grounded
surface. An electronic device exposed to ESD may not be affected at all and can work perfectly throughout a
normal cycle but may degrade during the life-cycle of the device.
Workstation
It is recommended that you work in a well-lit, static free area.
Before You Begin
Before beginning the disassembly process, please follow the preliminary steps below:
a. Power off the C202SA.
b. Disconnect the AC adapter from the device by unplugging the power cord.
c. Disconnect any external devices (ex: flash-drive, USB mouse, headphones).
Please use industry standard tools intended for PC repair purposes.
Suggested tools:
Pry Tool
Philips Screw Driver
Precision Tweezers
